Flash Player Sandbox Now Available for Safari on Mac OS X

Over the last few years, Adobe has protected our Flash Player customers through a technique known as sandboxing. Thus far, we have worked with Google, Microsoft and Mozilla on deploying sandboxes for their respective browsers. Most recently, we have worked with Apple to protect Safari users on OS X. With this week’s release of Safari in OS X Mavericks, Flash Player will now be protected by an OS X App Sandbox.

For the technically minded, this means that there is a specific com.macromedia.Flash Player.plugin.sb file defining the security permissions for Flash Player when it runs within the sandboxed plugin process. As you might expect, Flash Player’s capabilities to read and write files will be limited to only those locations it needs to function properly. The sandbox also limits Flash Player’s local connections to device resources and inter-process communication (IPC) channels. Finally, the sandbox limits Flash Player’s networking privileges to prevent unnecessary connection capabilities.

Safari users on OS X Mavericks can view Flash Player content while benefiting from these added security protections. We’d like to thank the Apple security team for working with us to deliver this solution.

Working Together on Keeping Our Mutual Customers Up-to-Date

No doubt, staying up-to-date on the latest security patches is critical in today’s threat environment. In addition to the many security initiatives we engage in as a vendor to help keep our products and our users safe, the single most important advice we can give to users is to always stay up-to-date. The vast majority of users who ever encountered a security problem using Adobe products were attacked via a known vulnerability that was patched in more recent versions of the software. This is why we’ve invested so much in the Adobe Reader/Acrobat update mechanism introduced in 2010, and more recently in the Flash Player background updater delivered in March of this year and used for the first time with last week’s Flash Player security update. Both update mechanisms give Windows users the option to install updates automatically, without user interaction. A Mac version of the Flash Player background updater is currently in beta and will be available very soon—stay tuned.

In the meantime, we welcome today’s initiative by Apple to encourage Mac users to stay up-to-date: With the Apple Safari 5.1.7 update released today, Apple is disabling older versions of Flash Player (specifically Flash Player 10.1.102.64 and earlier) and directing users to the Flash Player Download Center, from where they can install the latest, most secure version of Flash Player.

Remember: The single most important thing we can do to protect ourselves from the bad guys is to stay up-to-date. A thank you to the security team at Apple for working with us to help protect our mutual customers!
